SASI-I FRAME.

Application filed March 22, 1924;.

My invention relates to devices for closing the openings around the sheaves in sash pulleys, to prevent the entrance of air from the sash casing, especially in connection with the sash pulleys for the lower sash in the ordinary window frame constructions.

In such construction the sash frames for the sash weights are frequently left open at the top and as a result the cold air frequentlyfurnishes an objectionable draft around the pulley sheave, which is ordinarily without remedy except by tearing the casing apart and blocking the opening.

It is the object of my invention to provide a simple, cheap and effective means to close the sheave openings, which can be readily and easily applied by the householder and which at the same-time in no way obstructs the ordinary raising and lowering of the sash.

In the drawing:

Figure 1 is a front elevation of the upper end of the sash casing with my improved closure applied to the sash pulley.

Figure 2 is a vertical longitudinal sec tion of same.

Figure 3 is a front view of the upper closure plate.

Figure 4: is a similar view of the lower plate.

In the drawings I have illustrated only one of the sash casings as the casing on the opposite side is of similar construction.

The sheave 1 of the sash pulley is usually mounted in a pulley casing 2 which is fitted in a suitable opening near the head of the pulley piece 3 of the casing, and over this sheave runs the sash cord 4 attached to the window sash 5 at one end and carrying the sash weight 6 at the other.

Where the casing is open. a cold draft frequently enters around the sheave grooves.

To close these openings I provide an upper and a lower plate 7, 8, preferably of sheet metal.

The plate 7 is formed with a slot 9 of a width to slip over and loosely enclose the Serial No. '?01,041.

sheave from above, and the base of the .slot is semi-circular and preferably beaded at 10 to hug closely the sash cord 4 without preventing its movement.

The plate 8 is formed with a correspond ing slot 12 to loosely lit the sides of the sheave from below and the base of this slot is formed with a tongue 13 to loosely fit the groove 14-, of the sheave.

The inside bead 15 and parting strip 16 are lifted and the two plates inserted fiat against the pulley piece and the bead and strip returned and nailed in place to hold the closure plates, or the plates themselves may be nailed in position. The slots in the two plates are preferably of such depth that when adjusted in position they will slightly overlap as indicated in the drawing.

In this way a perfect air closure for the grooved sheaves may be provided which can be readily and easily applied by anyone without opening up or tearing out the sash frame to close' the casing.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In combination with the pulley casing and sash pulley mounted therein, of a pair of separate and independent plates of sheet metal adapted to be readily secured to the pulley piece, and said plates correspondingly slotted to form a continuous slot to permit the pulley sheave to project therethrough, while loosely embracing the sides and groove of the sheave to enclose the sheave openings.

2. In combination wit-h the pulley casing and sash pulley mounted therein, of a pair of separate and independent plates of sheet metal adapted to be readily secured to the pulley piece, and correspondingly slotted to form a continuous slot to permit the pulley sheave to project therethrough, the base of one slot curved to embrace the sash cord and the base of the other slot provided with a tongue to engage the sheave groove to pro vide a complete closure for the sheave.
